WATER-SHED FOR CELLAR-DOORS.

SPECIFICATION forming part of Letters Patent No.7ea275, dated June so, 1903.

Application filed April 6, 1903. Serial No. 151,267. (No model.)

For protecting cellars and caves from water I have provided the entrance-doors with a pivotally-mounted plate arranged to cover an opening at the upper end of inclined doors and shedthe water and adapted and.

provided with means by which the opening and closing of the doors will cause the plate to be rocked on its pivot-s to raise it free of the door in being opened and closed and ,to be depressed to cover the opening to shed the water by the closing of the door.

I11 the accompanying drawings, in Figure 1 I have represented an inclined cellar-door provided with an automatic opening and closing water-shed at its upper end. Fig. 2 is a vertical longitudinal'section of the door with the pivoted Water-shed closed down over the opening at the upper end of the door. Fig. 3 is a like view showing the pivoted water-shed in its raised position when the door is open. Fig. 4 shows the spring-sustained rod and its fixed bracket.

Cellar and cave doors are usually set inclined, so as to shed water, and to prevent water leaking or entering through the opening at the upper end of the door I provide a self opening and closing water-shed for this opening. This movable shed consists of a plate 1, arranged across the cellar-opening at its upper end and having apivot at each end mounted in brackets 2 011 the side frames of the door, so that the pivots will be abovethe end of the door. The plate is curved or so formed transversely as to extend below the line of the pivots and overhang the end of the door, to lie flat on its outer side, and to cover an opening at the end of the door and to extend above the line of the pivots up into a wall-recess when the door is closed, thereby overlapping the door at its upper end and forming a cover for the opening at the wall and a water-shed for this end of the door, and for this purpose the door need not extend close to the wall. For automatically raising and-lowering this water-shed to allow the door to be opened and closed free of it I provide connections with the water-shed arranged and adapted to operate it by the opening and closing of the door. To that side wall of the cellar-openin opposite the hinges at which the door opens and closes is fixed in wall-brackets 3 a rod 4:, sustained by a spring 5 on the rod between the lower bracket and acollar on said rod, so that the upper end of the rod will be maintained in its normal position to be struck and depressed against the tension of the spring by the closing of the door. A link 6 is pivoted in position to the cellar-wall and is connected at one end to the spring sustained rod, and at its other end is pivoted the lower end of a vertical rod 7 which is pivoted to that part of the watershed plate which extends upward into the Wall-recess. The cellar-door in being closed presses down the spring-sustained rod and by the link connection with the latter raises the vertical rod, thereby forcing the rear projecting part of the water-shed plate upward and, rocking it, forces its front projecting part downward upon the cellar-door, thereby closing the opening at the upper end of the cellar-door and shedding the water over its upper end. On opening the cellar-door the spring-sustained rod, by the upward pressure of said spring on a collar 8 of saidrod, will be forced by the tension of the spring upward by the connections of the rod with the watershed plate, whereby the latter will be caused to be rocked, pulling down its rear projecting part and raising its front projecting part to clear it of the opening door.

I claim- 1. Awater-shed device for cellar-doors, consisting of a plate pivotally mounted on the door-frame at the .upper end of the door, and a spring-sustained rod, connected with the plate and arranged to be depressed by the closing of the door to force the plate down and hold it upon the door and to pull the plate up and hold it when the rod is released of pressure by the opening'of the door.

2. A water-shed plate for cellar-doors pivotally mounted to cover an opening at the upper end of the door and adapted to overhang the upper end of the latter and to enter a wall-recess, in combination with means for rocking said plate to force and to hold its overhang part upon the door, and to raise and hold it free of the door consisting of a rod pivotally connected to and depending from the shed-plate, a link pivoted to said depending rod, and a spring-pressed rod pivoted to said link and arranged on the cellarwall in position to be depressed by the closing of the cellar-door and to be freed from pressure by the opening of the cellar-door.

3. In a water-shed for cellar-doors, a plate pivotally mounted onthe door-frame as a cover for an opening at the upper end of the door and adapted to overhang its upper end, means actuated by the closing of the door to depress 15 the pivoted plate in closed relation with the door, and means actuated on the opening of the door to raise the pivoted plate out of the Way and to maintain it raised.

In testimony whereof I aifix my signature :0 in presence of two witnesses.
